A Seagoville home was targeted twice by armed robbers over a span of 17 days, police say.

Apparently different groups of armed men entered the home on Oct. 18 and Nov. 5. Surveillance cameras inside the home show the men in both instances going up a stairway.

In the first incident, a group of four men entered through an unlocked door while a woman and her children were home, police said. The suspects demanded money from her, and ultimately took “an undisclosed amount of money” and the woman’s purse.

Video, released “as a matter of public safety,” shows three men going upstairs to the home’s second floor. Two of them appear to have guns and are covering their faces. A third removes a hoodie at the top of the stairwell.

The woman and children were uninjured.

On Nov. 5, robbers apparently broke into the same house while no one was home. Three men can be seen on video climbing the stairwell. One suspect was armed.

It was not clear whether anything was taken from the home during the November incident. Police say a motive remains unclear in either case.

“Investigators have spoken with the adult residents of the home and neither the woman, nor her boyfriend, claim to have any knowledge as to why this house has been targeted twice by armed suspects within a matter of a few weeks,” read a release from Seagoville PD.

An investigation is ongoing.
